I got this by mistake - thought I was ordering the famous 1946 anthology edited by Healy and J. Francis McComas, but in fact it is a 1951 followup edited by Healy alone. For all that, I was not too disappointed, at least given my expectations of an original sf anthology of the period; there are average quality stories by Ray Bradbury, Isaac Asimov, AE van Vogt and a half dozen others who I haven't heard of, and the first publication of Anthony Boucher's classic "The Quest for Saint Aquin". Apart from that, the other one that really grabbed me was "Bettyann", by someone called Kris Neville whose work I don't think I otherwise know. It is the longest story in the book, about a Mid-American teenage girl who is forced to confront her own always half-suspected nature as an alien changeling; excellent, I thought. Is Neville's other stuff worth pursuing?
